Fun Between Siblings

As Zack continued to grope his sister’s big tits and Heather was loving every minute of it. After doing this for a bit, Zack decided to change things up a bit and he moved his mouth down to Heather’s right boob and took her nipple in his mouth and started to lick and suck on it while using his free hand to continue to stimulate her left boob.

Heather was really starting to get horny now, which caused her to push down her bikini bottom while Zack continued to play with her tits. Zack felt his sister push down her bottoms and the next thing he knew, Heather was stroking his cock through his swimsuit. He moaned onto her nipple and then he decided to move over to her left boob and give it the same stimulation that he had her right one.

“Oh, it feels so good, big brother!” Heather moaned.

Zack smiled around her nipple and then he pulled away, which brought a groan of frustration from Heather. Zack then moved in to kiss his sister and she willingly gave into the kiss as she felt Zack moving her to the bed. Once the two of them reached the bed, Zack pushed Heather back so that she was now reclined on the bed with her legs hanging over the edge and her pussy right where he wanted it.

Zack dropped to his knees and wasted no time in attacking Heather’s wet pussy. She let out a loud moan as soon as Zack’s tongue made contact with her wet folds.

“Yes Zacky, eat my pussy!” Heather moaned out loudly and Zack didn’t even stop what he was doing to answer her.

Zack started to thrust his tongue in and out of his sister’s tight pussy and Heather was loving every minute of it. Heather knew that she wouldn’t last long at the way that Zack was going at her, but she was fine with that. The quicker she has an orgasm, the more it is possible for her to come more than once.

“Oh yes! I’m getting so close!” Heather moaned.

At hearing this, Zack changed his tactic and moved his tongue up to her clique and inserted two fingers inside of her pussy. After a minute of this, Heather knew she couldn’t hang on any longer, so it was no surprise to her when she felt her orgasm come on.

“Oh shit! I’m cumming!” Heather just about screamed at the top of her lungs.

She gushed all over Zack's face and when she finally came down from her orgasm, Zack pulled back and smiled at his sister as he cleaned off his face with his hands and tongue. Heather smiled back at him and stood up off of the bed and got on her knees in front of her brother. She loosened his pants and pulled them down and his dick was now out in the open and she couldn’t help but laugh when it about smacked her in the face once it was out of the confines of Zack’s swimsuit.

“It’s always nice to about get smacked in the face with a big cock.” Heather said as she started to stroke Zack with her hand and then she dove in and started licking up and down his cock from base to tip.

“So good!” Zack moaned out as his sister finally took half of his cock into her mouth and she continued to bob up and down his length.

Heather was doing a good job of keeping Zack on his toes. She started out slowly, but after a few minutes she sped up to the point that Zack thought that his sister might have had superspeed. After a bit of the fast motion, Heather changed things up again and started to go slow. The only difference was this time she was taking more of him into her mouth until Zack felt his sister’s chin make contact with his nut sack. She held it there as long as she could as she looked up at him with her eyes at the same time. It was one of the sexiest things he had ever seen.

“So deep!” Zack moaned and Heather winked up at him as she pulled away long enough to catch her breath.

Heather didn’t waste any time getting back to work on sucking her brother’s cock. Now she was in constant motion, but she was taking him all the way into the back of her mouth and down her throat with every bob she made.

Zack was in pure bliss. The only person who might be better at sucking cock then his sister was, was probably Sharon. He would have to put that theory to the test once Sharon finally loosened up and decided to have fun with a girl.

“Fuck!” Zack moaned as his sister continued to suck him off.

“You like that don’t you, big brother?” Heather asked, but she didn’t wait for the answer as she went back to taking all of his cock into her mouth and throat.

Heather sucked on Zack for another few minutes and she could tell that he was getting close to cumming. She knew how close when Zack finally spoke up.

“I’m going to cum soon!” Zack moaned and that was the cue for Heather to pull back.

Once she pulled back and Zack moaned in frustration, she just smirked up at him and she stood up and kissed her brother on the lips. After a few minutes of that, Heather pulled back from the kiss as well.

“We can’t have you cumming yet. I have other plans for you.” Heather said as she pushed her brother back toward her bed and he fell onto it.

Zack climbed up the bed so that he was now comfortable. Heather crawled up his body, kissing him the whole way. Once she made it up to his face, Heather kissed him on the lips and then reached back behind her to line his hard cock up with her slit.

“I guess it is a good thing that I can recover my stamina pretty quickly.” Zack said and Heather smiled at him.

“Yes, it is a very good thing.” Heather said as she sunk down on Zack’s cock and both of them groaned at the pleasure that they both felt.

Once Heather got used to Zack’s size, she started bouncing up and down on top of him. Zack couldn’t take his eyes off of his sister bouncing tits. He just had to get a hold of them again. He reached up and started to grope both of her huge tits and this was much to Heather’s liking as well.

“So good!” Heather moaned.

“So tight!” Zack moaned back to her.

Once Heather got the rhythm that she wanted, she realized that Zack was now meeting her thrust for thrust and she was feeling even better now than she was when it was just her doing all of the work. The two were always in such good sync with each other. It was like they knew what the other wanted. Heather guessed that it had something to do with being twins.

Soon things sped up between the two of them. They were both fucking hard right now and that was causing Heather to get louder and louder as time went by.

“You’re getting close again aren’t you?” Zack asked his sister.

“So close! Don’t stop!” Heather moaned back to her brother who picked up his pace even more now.

Heather knew that she was going to last much longer so she started to go faster as well. She didn’t know if she would be able to finish her brother off right now, but she was sure as hell going to try.

“Are you trying to make me cum, sis?” Zack asked.

“Well, yeah.” Heather said.

“Try all you want. I still have more left.” Zack said and hearing that he had more to give for some reason sent Heather over the edge again.

“Fuck! I’m cumming!” Heather moaned loudly.

Once she came down from her high, Heather collapsed on top of Zack, trying to catch her breath. Zack continued to thrust inside of her while she was laying on him. He felt when Heather was ready again because she started to move a bit on top of him again. Soon, Heather pushed herself up and smiled down at her brother.

“That was great, but I didn’t get any in my ass last night.” Heather said and Zack understood immediately where she was going with this.

Heather rolled over onto her back and got into position so that her brother could fuck her ass. Zack got in between her legs and lined his wet cock up with her tight back door and pushed some of his length into her slowly. He continued this until his nut sack hit against her ass and he couldn’t go any further.

“So big!” Heather moaned as Zack started to move slowly in and out of her.

Heather now had her legs up on Zack’s shoulders which was allowing him to get deeper inside of her. Zack soon picked up his pace because his sister had loosened up enough that he wouldn’t hurt with the speed.

“Yes, big brother! Fuck my ass!” Heather moaned out.

“You like the way I fuck your ass?” Zack asked and all Heather could do was nod.

Zack decided to go even faster now and that was when Heather got even louder than she already was. Thank God for insulated rooms Zack thought to himself as he continued to pound his sister’s ass.

Heather was in a position that she couldn’t do anything to really help her brother out, but it didn’t look like he needed any help, so she just laid there and let Zack have his fun. She reached down with her hand and started to rub her pussy, which was quickly pushing her toward her orgasm again.

“I don’t think I am going to last much longer, sis!” Zack moaned.

“Me either! Cum in my ass, Zacky!” Heather moaned and that was all Zack needed to fall over the edge.

Zack shot load after load into his sister’s ass and that was what finally pushed Heather over the edge for the last time in this session.

“Fuck!” Zack moaned as he came in his sister.

“I’m cumming!” Heather moaned as well.

Zack collapsed on Heather, but he didn’t stay there long as he rolled off of her and they both laid there for a few minutes until they finally caught their breath. “I guess we better get dressed and get to the others before they start to wonder where we are.” Heather said.

“Yeah, that is probably a good idea.” Zack said as the two siblings got up and started to get dressed.

They both looked at each other in the mirror and made sure they didn’t look like they had sex before leaving the room and making it out to the other.

. . .

As Taylor was walking by her sister’s room on the way to meet up with her family, she heard moaning from her room, so she made her way to the door and opened it. She figured since she had sex with Heather and Brandon the night before, they wouldn’t mind if she just walked in.

As she walked into the room, she heard something that surprised her.

“Yes, big brother!” Fuck my ass!” She heard Heather moan.

She looked closer at the couple and realized that it really was her brother that was fucking her sister. She couldn’t believe her eyes. She never thought that her siblings would ever do something like this, but as much as she wanted to be disgusted, she couldn’t help but watch for a bit longer. It was hot and she couldn’t deny that. Then she thought about how she had sex with her sister the night be fore and how fun it was, even though it was wrong. She thought about whether she should have sex with her brother at some point as well. She had already crossed the **** line, why not do it again at some point. Plus, it looked like her brother was hung, which is always a good thing. She knew she had to leave soon though or she would get caught and the moment her siblings came gave her that window to leave the room quietly.

“What the hell did I just see and why did it turn me on?” Taylor asked herself as she made her way down to the main level of the house to meet up with everyone else.

She would have to look more into this later.
